Quick and dirty debugging output for tired Go programmers

q

q is a better way to do print statement debugging.

Type q.Q instead of fmt.Printf and your variables will be printed like this:

Why is this better than fmt.Printf?

• Faster to type
• Pretty-printed vars and expressions
• Easier to see inside structs
• Doesn't go to noisy-ass stdout. It goes to $TMPDIR/q.
• Pretty colors!

Basic Usage

import "github.com/y0ssar1an/q"
...
q.Q(a, b, c)

// Alternatively, use the . import and you can omit the package name.
// q only exports the Q function.
import . "github.com/y0ssar1an/q"
...
Q(a, b, c)

For best results, dedicate a terminal to tailing $TMPDIR/q while you work.

Install

go get -u github.com/y0ssar1an/q

Put these aliases in your shell config. Typing qq will then start tailing $TMPDIR/q.

alias qq=". $GOPATH/src/github.com/y0ssar1an/q/q.sh"
alias rmqq="rm $TMPDIR/q"

Editor Integration

Sublime Text

cp $GOPATH/src/github.com/y0ssar1an/q/qq.sublime-snippet Packages/User/qq.sublime-snippet

Atom

Navigate to your snippets.cson file by either opening ~/.atom/snippets.cson directly or by selecting the Atom > Open Your Snippets menu. You can then add this code snippet to the bottom and save the file:

'.source.go':
  'q log':
    'prefix': 'qq'
    'body': 'q.Q($1)'

VS Code

In the VS Code menu go to Preferences and choose User Snippets. When the language dropdown menu appears select GO. Add the following snippet to the array of snippets.

"q.Q ": {
	"prefix": "qq",
	"body": [
		"q.Q($1)"
	],
	"description": "Quick and dirty debugging output for tired Go programmers"
}

vim/Emacs

TBD Send me a PR, please :)

Haven't I seen this somewhere before?

Python programmers will recognize this as a Golang port of the q module by zestyping.

Ping does a great job of explaining q in his awesome lightning talk from PyCon 2013. Watch it! It's funny :)

FAQ

Why q.Q?

It's quick to type and unlikely to cause naming collisions.

Is q.Q() safe for concurrent use?

Yes
